PIPE-ORGAN.

$EHCIFIOATION i'orzning part of Letters Patent No. 343,049, dated June1, 1886.

Application filed July 3, 1885.

To aZZ whom it may concern:

Be it known that I, MA'rnLis P. MULLER, a citizen of the United States,residing at Hagerstown, in the county of \Vashington and State ofMaryland, have invented a new and useful Improvement in Pipe-Organs, ofwhich the following is a specification, reference being had to theaccompanying drawings.

Myinvention relates to organs, and particularly to that class known aspipe-organs, the object being to construct the same of two sections, onecarrying a bank or banks of keys and the other section theorgan-action,whereby the organ may occupy but a minimum amount'of spacefor transportation, and may be readily carried through a door ofordinary size without taking the organ to pieces, as has heretofore beennecessary.

A further object of the invention is to provide a pipe-organ with aseriesof detachable pipes, and with a hinged support for the same, whichsupport is adapted to be folded to economize space in transportation.

A further object of the invention is to provide improved means forleveling the keys when any one of the same drop below the others of thebank.

Vith these ends in view the invention consists in the improved.construction and combination of parts hereinafter fully described, andpointed out in the claims.

In the drawings, Figure 1 is an end elevation of an organ embodying myinvention with the end removed. Fig. 2 is an end elevation of two of thewind-pipes. Fig. 3 is a bottom view of the same, showing the arrangementof valves. Fig. 4 is a detail. view showing the hinged portion of thepedal air-passage thrown up. Fig. 5is a detail view of means employedfor leveling the keys.

In the accompanying drawings, in which like letters of referenceindicate corresponding parts in all the figures, A represents the organ,which is constructed of two sections, B and G, the section 13 havingwithin it the organ-action and the section 0 carrying the key boardorboards and the pedals. Asa means of attaching thesection C to sectionB, Ihave shown said section G provided with L-shaped hooks projectingfrom the rear side thereof, which hooks are adapted to engage openingsin the section B. I have shown this form of attach- Serial No. 170,027.(No model.)

ing means as the means preferably employed; but it will be readily seenthat there are nube detachably secured together; hence I do not wish tolimit myself to the construction shown.

In the event that but one bank of keys is employed, the key-board wouldbe of about the size shown below the dotted line a to, exclusive of theornamental moldings shown at b. In this case the board would be hingedor otherwise attached to section B at its upper end, so that it could beturned up against the taching the parts.

E represents the keys,whieh are so mounted midway their ends that theymay have a rocking motion, as usual, the inner ends of the keysextending into the section B.

D represents the pipes, which are arranged in series of threes, asshown, and at thelower ends of these pipes are provided air-chambers F,having in their bottoms openings 0. If one bank of keys is employed,there will be two openings, and if two banks of keys are employed threeopenings, the other opening being controlled by a valve operated by thepedal.

F represents the valves, which are arranged under the air-chambers F andare so supported midway their ends that when their front ends are raisedtheir rear ends will be lowered from the openings, and thus allow thepassage of air to the pipes. Arranged beneath the valves F are flatsprings d, which are adapted to hold the valves in place over theopenings 0, and prevent their accidental dropping or displacementtherefrom. In the series of pipes No. 1 the valves are connecteddirectly to rods, which are operated upon by the keys by raising saidrods, and thus lowering the valves from engagement with the openings;but in the series No. 2 the valves F are connected at their front endswith levers G, pivoted centrally by means of wires 6.

G represents the rods for operating the valves. In the series No. 1these rods are connected directly to the valves F, while in series No. 2they are connected to the front ends of levers G. Upon the upper ends ofthese rods are provided forwardly-extending blocks H, provided withvertical passages or openings, in which are located thumb-screws merousways in which the said sections might U same, thereby obviating thenecessity of def, upon the lower ends of which are secured leatherwashers having a covering of felt or similar material to deaden thesound. It will be seen that by lowering the set screws the front ends ofthe keys may be raised, so that should one of the keys drop below thelevel of the rest of the bank it may be raised by lowering theset-screws upon the inner or. rear end of the key.. 7

It will be observed that in the series of pipes numbered 1 that the flatsprings for holding the valves in position may be dispensedwith, fromthe fact that the rods G bear uponthe outer ends of the valves, and thushold their inner or rear ends in place.

Arranged below the pipes and their valves is an air-reservoir, H, fromwhich lead pipes I for supplying air to the chambers arranged below eachseries of pipes, and for supplying air to said reservoir is a bellows,J, arranged beneath the reservoir, as shown.

K represents the pedal, hinged or pivoted at its front end.

L represents a rod or shaftjournaled in the moldings b and connectedwith the inner end of the pedal by ashort arm, h. The innerend of thisred L is connected with one of the levers G by a rod, '5, so that whenthe inner end of the pedal is lowered it will lower the lever, whichwill overcome the spring and remove the valve from the opening andsupply air to the pipe.

Upon the under side of the organ is provided an air-passage or channel,M, at the rear end of which is a hinged section, N, extending.

beyond the rear end of the organ, which section is closed at its outerend, and is provided on its upper side with a seat or recess, 70, inwhich rests the foot lof one of the pedal-pipes m. These pedal-pipes mare detachable from the section B of the organ, and are preferablyattached thereto by hooks, as shown.

0 represents an air-passage leading from the air-reservoir to thepassage leading to the pedal-pipes. An opening is made in the passageleading to the pedal-pipes, and closing the same is a valve, P, attachedto the free end of which is a rod, g, which connects with a pivoted armconnected with the pedal, which arm is constructed and arranged similarto those described for operating the valves of the series of pipes 1.

By the construction before described a pipeorgan is provided whichpossesses great power and variety of tone, the detachable partsdescribed may be readily and easily separated from the body or mainsection of the organ, and readily attached thereto, the services of anorgan-builder or mechanic not being necessary for this purpose, as isthe case with organs as now constructed, wherein it is necessary toseparate the same for transportation and to allow it to be carriedwithin a building.

I am aware that organs have been made in detachable sections forportability, and the same is therefore not broadly claimed.

Having thus described my invention, I claim 1. A portable organ made insections detachably coupled together, comprising a body having theorgan-action, a section carrying a pedal and bank or banks of keys, theair-passage, and the pedal-pipes located without the body and incommunication with the air-chamber, substantially as described.

2. A portable organ made in separable sec tions adapted to be coupledfor operation and comprising a body having the organ-action, a sectioncarrying the pedal and bank or banks of keys,the air-passage having thevalve-chamher, and a flexible connected section eXtending beyond thebody, and a pedal-pipe fitted on a seat and in communication with theairpassage, substantially as described.

3. The combination, with an organ, of detachable pedal-pipes locatedwithout the same, as set fOllh.

4. The combination, with an organ having the air'passage, of the hingedsection supporting a detachable pedal-pipe, as set forth.

5. The combination, with an organ having the air-passage having thehinged section extending beyond the rear end of the'same, of thepedal-pipe resting on and communicating with the air-passage anddetachably secured to the body of the organ, as set forth.

6. The combination, with a key and its valve-connecting rod, of abearing-block secured to the rod, a vertically-adjustable shaft mountedin the block and having a thumbscrew, and an elastic washer rigidlysecured on the thumb-screw and bearing against the rear ends of the keyto level the same, substantially as described.

7. The combination of the organ-body, the e terior pedal-pipe, andair-passage, on which the pipes are seated and having the valvechamberat one end in communication therewith, a valve, the pedal, a pivotedlever connected to the pedal, and a link connected with the pedal andvalve,subst-antially as described.

8. As a device for leveling the keys of an organ or the like, a blockcarrying a thumbscrew adapted to bear on the rear ends of the keys, anelastic washer or disk on the end of the thumb-screw, and a felt or likecovering for the washer, as set forth.

In testimony that I claim the foregoing as IIO my own I have heretoaffixed my signaturein GEO. T. LEITER, ALEX. ARMSTRONG.
